Varizoom's VZ-Pro series gives you the highest degree of zoom control for nearly every acquisition situation. This is achieved by the precision dual potentiometers and unique zoom handle grip. By combining a pressure sensitive thumb control with a separate but easily accessed dial speed control, Varizoom's VZ-Pro series provides exceptional control. Set the high speed limit with the dial, and ramp up to that setting with the separate, super smooth thumb control. This uniquely styled device relieves the operator of having to hold and maintain just the right amount of pressure since the maximum speed is set by the dial .
(If you have a Fujinon 12-pin lens, order model VZ-PRO/F12)
